About 22% to 26% of patients with serous ovarian cancer present with germline or somatic BRCA1/2 mutations.6, 7, 8, 9 BRCA1 and BRCA2 are tumor suppressor genes that regulate the cell cycle and repair DNA double‐strand breaks via homologous recombination. This evidence concerns the gene BRCA1 and ovarian serous adenocarcinoma.
